Buying a used BMW Z4 exhaust manifold: what matters
Fitment on a used exhaust manifold varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:
- State whether it's petrol or diesel
- State the engine code if known

Fitment questions
Does the BMW Z4 have an exhaust manifold, or does it use a different setup?
Yes, all BMW Z4 engines — whether the four-cylinder or six-cylinder petrol units across the E85/E86 (2002–2008) and E89 (2009–2016) generations — use a conventional exhaust manifold to collect gases from the cylinder head. The Z4 was only ever offered with petrol engines in the UK, so there is no diesel exhaust manifold variant to consider. When searching for a used unit, your engine code is the critical starting point, not the trim or bodywork.
Will an exhaust manifold from an E85 Z4 (2002–2008) fit my E89 Z4 (2009–2016)?
Almost certainly not — the E85 and E89 are entirely different generations with different engines, different cylinder head designs, and different emissions calibrations, so the manifolds are not interchangeable. The E89 moved to newer turbocharged N-series engines such as the N20 and N52, which have fundamentally different exhaust routing compared to the earlier M54 and N52 units found in the E85. Always quote both registration numbers to the breaker and ask them to cross-reference engine codes directly before purchasing.
I have a 2009–2016 E89 Z4 — does it matter whether I pick a manifold from an sDrive18i, sDrive20i, or sDrive35i?
Yes, it matters significantly — these designations correspond to different engines (N20, N20, and N54/N55 respectively), and each engine has its own exhaust manifold design, so a unit from the wrong engine will not fit. The sDrive35i uses an inline six-cylinder with twin-turbo architecture that has a completely different manifold arrangement compared to the four-cylinder sDrive20i, so you must match by engine code rather than just displacement. Trim level names such as SE, Sport, or M Sport make no difference to manifold fitment — it is purely the engine code that counts.
Does the trim level — SE, Sport, or M Sport — affect which exhaust manifold I need for my Z4?
No, trim level has no effect on exhaust manifold fitment whatsoever — the manifold is determined entirely by which engine is fitted, and all trim levels within the same engine variant share the same manifold. An M Sport badge brings suspension, styling, and cosmetic upgrades but does not change the engine or its exhaust architecture. Focus on confirming your engine code with the breaker rather than worrying about trim designations.
My Z4 is a 2011 model — could I use a manifold from a 2009 car, or is there a facelift boundary that matters?
The E89 Z4 received a facelift in 2013, which brought some visual and equipment changes but did not introduce new engine families, so a manifold from a 2009 car is likely compatible with a 2011 car provided both share the same engine code. The key boundary to be cautious about is not 2013 but rather any mid-life engine code revision — always ask the breaker to verify the donor car's engine code against your own before buying. If your car has a catalytic converter integrated into or closely associated with the manifold assembly, confirm the full assembly specification with the breaker against your registration, as emissions-related components can vary in ways that affect MOT compliance.
How important is the engine code when buying a used Z4 exhaust manifold, and where do I find mine?
The engine code is the single most important piece of information — manifolds are machined to match specific cylinder head port layouts, stud patterns, and turbo or collector configurations, all of which vary between engine families. You can find your engine code on a sticker inside the engine bay, on the DVLA V5C in some cases, or by asking a breaker or dealer to look it up against your registration plate. Providing your full registration to the breaker at Findapart will allow them to identify the correct engine code and confirm the part matches before you commit to a purchase.
